I foolishly let them do whatever they wanted which took about four hours. It seemed that they were legitimate, so I went along with it. I talked them down from about $600.00 to $402.00, but did not give them any credit card info. I said I would send them a check in about a three months. Their fee was to cover my new firewall and anti-virus for the life of my computer. I do not intend to give them any money, but they installed their number on the lower right hand corner of my screen so that I could contact them in the future. If they call me looking for the money, they can wait until Hell freezes over. Boy, was I dumb to have even let them have a response from me initially. I guess we all are vulnerable at one time or another. This entire procedure wasted a lot of my time, but at least I still have my $402.00.
